IMPROVEMENT IN CAR-COUPl INGS.

Specification forming part of Letters Patent No. 135,849. dated February11, 1873.

To all whom it may concern:

Be it known that we, JOHN ROYAL, Mosns A. LENTZ, and JEREMIAH M.DEIBERT, of La Fayette, in'the county of Tippecanoe and in the State ofIndiana, have invented certain new and useful Improvements inCar-Gouplings; and do hereby declare that the following is a full,clear, and exact description thereof, reference being bad to theaccompanying drawing and to the letters of reference marked thereon,making a part of this specification.

The nature of our invention consists'in the construction and arrangementof a car-coupling, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which our inventionappertains to. make and use the same we will now proceed to describe itsconstruction and operation, referring to the annexed drawing-in which--Figure 1 is a perspective view of our carcoupling, and Fig. 2 is alongitudinal vertical section of the same.

A represents the bumper or end of the drawbar, in the roof of whichthere is a slot and groove, to. In this .slot is hung a pin, B, by meansof a bolt, a, passing horizontally through the bumper,sai(-l pinswinging back and forth in the, bumper. The lower end of the pin Bswings in a groove, 1), in the bottom of the bumper. 0 represents a barsliding in a mortise made in the bumper across the mouth of the same andacross the groove bin the bottom thereof, so as to form a stop for theforward movement of the pin B. D represents the ordinary coupling-linkwhich, when inserted in the draw-head, pushesthe pin B backward untilthe end of the link passes the same, when the pin drops down into thelink, and the link cannot be drawn out on account of the slide vOstopping the forward movement of the pin. 0n the under side of the slide(3 is secured a spring, 11, having two teeth or shoulders, t 'i, one ofwhich catches on the inside of the bumper to hold the slide in its placewhen inserted, and the other holds it when partially drawn out, so thatthe slide cannot be entirely withdrawn from the bumper. When partiallydrawn out the slide 0 is away from the groove 1), and will hence allowthe pin 13 to swing forward and uncouple the cars. I

Having thus fully described our invention,

what we claim as new, and desire to secure by Letters Patent, is-

The combination of the slide Cwith spring d and catches t t, theswinging pin B, and the mouth of the bumper in which is a slot to allowthe pin B to play, as and for the purpose herein set forth. g

In testimony that we claim the foregoing we have hereunto set our handsthis 27th day of November, 1872. I r J 0 EN ROYAL.
